Abstract. Lithium ion batteries are batteries that function based on the transfer of lithium ions between a cathode and an anode. Lithium ion batteries have higher specific energies than batteries made from other materials such as zinc and lead due to the relatively light weight and low density of lithium.
Lithium-ion Battery (LFP and NMC) Lithium-ion can refer to a wide array of chemistries, however, it ultimately consists of a battery based on charge and discharge reactions from a lithiated metal oxide cathode and a graphite anode. Two of the more commonly used lithium-ion chemistries--Nickel Manganese Cobalt (NMC) and Lithium Iron Phosphate
Lithium Iron Phosphate (LiFePO4) — LFP. In 1996, the University of Texas (and other contributors) discovered phosphate as cathode material for rechargeable lithium batteries. Li-phosphate offers good electrochemical performance with low resistance. This is made possible with nano-scale phosphate cathode material.

The energy density of lithium-ion batteries is in the range of 90-160 Wh/kg. The average volumetric energy density of lithium-ion batteries as per the statistics of 2008 was 55 watt-hours per liter. This has further increased to 450 watt-hours per liter by the year 2020. The progress from the year 2008 to 2020 is shown in the graph below.
The Basics. A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator. The movement of the lithium ions creates free
The result was a lightweight, hardwearing battery that could be charged hundreds of times before its performance deteriorated. The advantage of lithium-ion batteries is that they are not based upon chemical reactions that break down the electrodes, but upon lithium ions flowing back and forth between the anode and cathode.
This intercalation chemistry, as he demonstrated subsequently in Science in 1976, enabled the first rechargeable Li battery, which consisted of a TiS 2 cathode and a metallic Li anode 2.
Rechargeable batteries. Li-ion batteries are now used in very high volumes in a number of relatively new applications, such as in mobile phones, laptops, cameras and many other consumer products. The typical Li-ion cells use carbon as the anode and LiCoO 2 or LiMn 2 O 4 as the cathode. The first commercial Li-ion cell

Lithium-ion batteries are ubiquitous in our everyday lives—most of us carry one around in our phone. There are several types of lithium-ion batteries. The
The greatest advantage of the lithium-ion battery is that the ions are intercalated in the electrodes. Most other batteries are based on chemical reactions in which the electrodes are slowly but surely changed. When a lithium-ion battery is charged or used, the ions flow between the electrodes without reacting with their surroundings.
